Updated pics of CJ5 frame restoration

i have a Lincoln 3200HD and right now im running .025 with gas...

before i was running .035 flux core because i didnt have my bottle yet...

hmmmm...

push instead of pull...

i'll have to try that...

i DID make some good welds on my table though, i'll have to send you a pic... only problem is, i made them after making butt ugly ones for about 1.5 hours before

whats a good pressure for gas to be run at?

i have a 20cf bottle and im running about 22-25 right now, seems to be working ok i guess... and i noticed that with gas, you have to turn the feed speed up cuz it cooks a whole lot faster

 

Yes, anytime you're doing any type of welding that requires a shielding gas (MIG and TIG), whenever possible, push the MIG gun/TIG torch. The job of the shielding gas is to push our natural oxygen out of the way. Our oxygen will contaminate the welding environment. So, by pushing, the gas is forced out ahead of where you're welding, clearing a path. If you drag the gun, you're directing the gas over the weld that you've already done. There are exceptions to every rule, and one exception is when welding thin gauge sheet metal downhill, to angle the gun upward and drag the weld downhill.

22-25 cfh is fine, as long as you're not getting any porosity.

The reason that you had to turn the feed up is because of the smaller diameter wire. .025 wire is good for bodywork, and other very thin metal (up to about 1/16" thick). Also, the thinner the weld wire, the more expensive it is.

For 1/16" to 1/4" (which is the max I'd probably weld with your machine) , I'd recommend .030. wire. With .030 wire, you'd have to turn your wire feed speed DOWN, from what you run the .025 at.

Half the battle with getting good welds, and not getting frustrated, is getting the machine set right....the voltage, and wire feed speed. This takes experimentation.

How thick is the metal of the table that you're building?

BTW...we should probably get a separate thread going on different welding techniques, ideas, etc.

I like the way you used a wire to hold the nuts to weld in. I just finished boxing my cj-5 and I didn't think of that, it would have been quicker than my method, ie, cut a through hole, drill and tap a plug in the lathe, and weld in from both sides, then grind smooth on the outside.

 

Yeah, but you have much deeper threads! Also, the wire holding the nut only works if there is a place to feed it into the frame, like another convenient, nearby frame hole.

 

agreed on the separate thread... i'll start a new one
